brushless 1/5 4wd conversion about to begin! couple questions.

[Metallover]

Do you have the motor plugged in? Properly? Maybe try plugging in the battery with the turorrle held all the way down on the transmitter. Have a separate bec plugged in?

Don't know why I'm saying all this... Doubt you're doing anything wrong. You're experienced enough. Wonder what castle says.

Edit- Looked at the led meanings sticky in the cc forum. It only says it's for car controllers, but it might be somewhat universal. Solid red or green means full throttle or reverse. Doubt the little flash of hape you got was that, but it might be. Maybe you have the rx plug plugged in backwards?

i will check the led meanings. i have checked and re-checked the to make sure its plugged in right and polarity etc. i cannot see anything i am doing wrong? i wish it was something i am overlooking so then its just a quick fix but it seems to be a problem with the esc. i mean, i hooked it up exactly the same twice and one time it worked fine with the MMM and the other time nothing on the HV. i also have test this with the rx and the same thing happens. everything is fine when i hook to my MMM but nothing happens when hooked to the HV.

castle hasnt responded yet to any of my calls or emails. maybe i will hear back tomorrow.

edit: so i checked the sticky with the led definitions and there is not a definition for a 1 second red blink and then nothing. i take that to mean there is something wrong. thanks for your help though metallover. even now i am still open to more ideas. i guess i just want to hang on to the hope that its just something i am overlooking so i dont have to send it in and wait 2 months.

Well, kinda similar problem I have.... my 2280 is sitting pretty in the firehammer, and have no ESC that could handle the current.. Been toying with the MGM for months... Mine takes programming, but nothing else...

which mgm did you buy? i know they arent cheap. plus i hear getting them fixed is a pain being as they are located in europe. it almost sounds like that little hobbywing is the way to go. didnt you say that your specs showed you werent even drawing 100amps?

btw, i dont really understand all the details of of gearing and watts and on and on. you seem to know all that very well. here is what i am running. was wondering if you could tell me if you think the hobby wing will work

2215 2y 750kv
10s 5000mah 30c
and 15/40 gearing

i know the gearing is high. i can go a bit lower down to a 12t pinion for a 12/40 setup if needed. is that gonna be geared low enough? what would my gear ratio be? remember i dont have the drive reduction unit like you. just a spur and pinion gear and of course the stock front and rear diffs which are 30t spur and 10t pinion.

roughly 7.5 final drive ratio has been the most I've been able to push/try on the 100A ESC without any issues.. but my KV is set for 356, and your's is 750KV.. but your tires are smaller diameter... and your vehicle is quite lighter in mass... your's is about 9.99:1 final drive ratio if you use a 12T pinion... I think yours is setup same as Kaz..? With the buggy tires and the high FDR and higher KV motor/rpm, I think the 100A ESC would handle fine...

I bought the 28025 temporary for my 1/5th scale race a few months ago, but it didn't work.. it was pretty much a waste of money since that's the only ESC that would've been able to handle the 2280-5 on 6S 10000 mAh, 5th scale.., and it still doesn't work, I'm sure Mike would help me out.. Just waiting for a reply.. I'm in the same boat as you, I really don't want to send it out, unless I'm 200% sure that there is nothing else that could be done for it to work.... because my Hydra 240 on 6S couldn't handle that motor either, but that's because it needed water cooling and the motor RPM was 1480KV...

The Hydra was 75+ Deg. C, the Lipos were about 50 Deg. C 6S2P 10000 mAh, and the motor was about 40 Deg. C. and all 6 10 AWG wires were warm...

Hyperion to the rescue... http://www.allerc.com/product_info.p...oducts_id=2821

Good for 10S, all e has done VERY well by me, ships from AZ to NY in 2 days, everytime!

[lutach]

Best to use a 1/5 scale Rx pack.

it says that hyperions is good for 10s or 40v but 10s is actually 42v so i am not so sure about that. the medusa bec is good 45v or 10s which makes more sense. its on backorder with allerc.com though. i will have to find it somewhere else.

so the bec has to be hooked up to the 10s pack? it doesnt just connect to the 2s rx pack and then the reciever?

lol If Hyperion says 10S, it's good for it. I did notice that it said 40 and not 42 volts, kinda strange but I'd ignore that.

For input it says 8-40 volts, so 2S is fine.

Lutach, I am a RX pack user, but only because I haven't bought the Hyperion BEC yet!

The Rx pack is the safest bet specially when using those huge servos in the 5th scale.

[Ryu James]

ok, so my LHS has the Castle BEC Pro which is good for up to 12s. i am going to get it now. one question though, do i need a rx pack and the BEC or just one or the other?

I would use a 14.8 Volt 4000mah pack with a UBEC.. weights less than 5 NiMH and more wattage.. Plus you could run fans off of it as well(If you wanted to)..

whats a ubec? man, i am getting confused. i need to sit down and learn more about this stuff. i do have fans that i will need to run. i have always used y-harnesses in the past to run my fans. whats another way of powering fans with the ubec?

I thought this new big high torque servos were meant for 2S lipos.

Like those $200 JR hi-volt servos?

I'm sure they are well worth it, but most RXs still won't support over 6V to my knowledge- so that makes it a problem.

James, most any brushless fan will be fine up to about 75% over spec'd volts. And wow do they work. Buddy of mine has 2 2" BB fans rated 12V, run on 16.8 normally, and have been run at 25V, no issues. I have 2 1" Novak fans rated at 5V, running 8.4 for over 3 years. No worries!
